CPT & HCPCS Codes:

CenCal Health, through instructions received from the Department of Health Care Services, implements CPT and HCPCS code updates each year. However, because of the time required for the State to determine rate and benefit status for each new code, Medi-Cal does not recognize new, deleted or changed codes on January 1 of each year.

Once these determinations have been made, usually in late summer, notification will be sent to Providers which will announce the date of service in which the new codes may be utilized. Because of this delay, it is important not to submit new codes to the Medi-Cal program until notified of such.  In the same light, Providers should also continue to use deleted codes until notified to discontinue.

Healthy Kids/Health Families/AIM

The Authorization and Referral process outlined in the Provider Section under “Authorization” in CenCal Health’s website applies to all Lines of Business.

Procedure Code Tips

Providers must use the HIPAA Compliant CPT, HCPCS codes and modifiers for the date(s) of service on the claim.

To verify that the service being provided is for an appropriate diagnosis, please contact your Claims Service Representative for assistance.

Claim Adjudication Edits

CenCal Health employs industry standard edits for all lines of business when adjudicating a claim. Most are standard edits such as verifying the member’s eligibility, whether or not the services billed are plan benefits, the validity of the codes submitted, and if authorization requirements have been met. In addition, there are claim edits set forth by the Department of Health Services related to Medi-Cal benefit limitations that may affect editing.

For All lines of business CenCal Health also utilizes the procedure-to-procedure (PTP) NCCI edits that are published by CMS.

Billing Tips

Avoiding claim denials and reductions in payment

  • Claims submitted with dates of service prior to July 1, 2016, will be denied;
  • Verify eligibility before rendering services and submitting your claim. Members who are not Medi-Cal eligible will be denied;
  • Referral Authorization Forms (RAF’s) are required when the provider is not the members current PCP;
  • Medi-Cal billing timelines apply. Claims received with dates of service beyond 6 months without a valid delay reason code will be reduced in payment;
  • Do not resubmit a new claim when making a correction to a previously submitted or denied claim as this can result in a duplicate claim denial.

Please contact your Claims Service Representative for all corrections, inquires and/or questions on your CHDP claims.
